Best sub for music,


Not HT, repeat not the boomboomboom of HT  effects.  which does not offer the high fidelity of musical sub bass (20hz-40hz) 
I'd have to go with the seas W26E001. which has a magnesium/aluminum cone. 
What that raitio is, not sure, seems 50/50. 
None of us here like the sound of those old aluminum cones. But my guess is Seas had to incorporate some alumium inorder to gain the 20-30hz and also mabe keep costs down. 
This YT vid says **Aluminum cone** which is confusing YTers.
Its a  composite, and perhaps the best ture woofer on the market.
Been around for ages, still hard to beat for pure natural low mids. .
Magesium is the best material to keep unwanted resonances out in the  60-1k range, very low/hardly measurable distortion. 
The issue here  tops out at 1k, so its really a  sub. 
This woofer may be a  good candidate to pair with a  5 inch wide band.

Having talked myself out of "no sub is the best sub' (based on multiple sub failures) I was willing to try again based on the sheer logic of roll off on Klipsch Lascala under 50 hz. (But what can possibly be added with such a low frequency?) A LOT or so I am hearing. I think my sub negativity was based on sloppy subs.  Velodyne, Boston Acoustics, Sunfire, all complete fails. Blobby, sloppy, intrusive, distracting, these sub par experiences turned me sour on the whole idea. Ladies and Gentlemen, I introduce you to SVS subs. Bought the sealed box SB-2000 pro thinking to probably upgrade with Crutchfield deal. Only $800. Crazy cheap, expected to be wasting my time. Hard to express how wrong i've been to avoid a quality subwoofer. Added super AC cord (helped alot!)  
I have buddy working on 60 inch woofer be power with 10 watt tube amp and hit hard like you mother wrap that guy in the head with monkey wrench when he try to take you daddy 76 caddy hub cap. Big time bass roll from this woofer shake you like I shake my wife sister after workout in my basement after rocking to my Maggie system. You no need big power with big tool.
Interesting feedback reading over this and general agreement which does not often happen here.

So 2+ subs are preferred for music and essentially any high quality brand will work well.
I confirm this by mixing 2 Scansonic driver based subs with a Martin Logan 212 for a large room.
